I know, I already raised my concerns regarding the new workflow, so I
won't repeat that. I can understand (too some degree) that we don't want
code to change just before the new merge window opens.

But I do wonder if we really don't even want to do subject+description
updates. Sure, the commit IDs will change. Who cares?

Anyhow, it is what it is.
